Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

5 Golang Libraries You’ll Wish You Knew Sooner
Testify simplifies writing unit tests in Go. The standard testing package is fine, but Testify adds assertions, mocking, and suite support, making tests more readable and maintainable.

From Vibe Coder to AI-Assisted Architect
I prefer to use the Go library testify, which significantly simplifies the code:

Building and Deploying a New API (Part 1)
nil is returned initially, as we're creating user_test.go and using Testify to create tests as we shape the behavior of PostUser. We don't have a DB wired up yet, so the responses will simply be hard-coded structs of what we expect the API to respond with for now to pass the tests.

Full Introduction to Golang with Test-Driven Development
This article is too basic and does not introduce anything you'd encounter in a typical Go project. If you want introduction to Go testing I recommend just reading the official docs https://pkg.go.dev/testing and understanding how to write table driven tests - https://go.dev/wiki/TableDrivenTests.
Going beyond what's built in, get familiar with https://github.com/stretchr/testify as that's used a lot.

Why I don't use a third-party assertion library in Go unit tests
Of course, as soon as people saw this, the third-party assertion helper libraries started appearing. The most popular one seems to be testify (although I've never used it). Personally, I thought that the explicit check would be good enough for me, but it's true that after writing a bunch of tests, the boilerplate does seem unnecessarily verbose.

Visualizing Diffs The Myers difference algorithm
This made me think of a couple other interesting things:
1. you can change which algorithm is used in git diff as multiple are supported

How do you do DB preparation in e2e tests?
Assertion libraries that people seem to love: - testify (my favorite) - go-cmp is a more barebones library - gotest.tools -- I have never used this but some swear by it

What annoys you about Go?
When I use functional arguments, I either prefix all of the options with the same prefix or put them in a dedicated package (like cmpopts) to help the IDE.

What are your favorite packages to use?
oklog/ulid to generate IDs. coreos/go-oidc for validating JWTs I get from auth. google/go-cmp for comparing structs in tests (unless the project is already using Testify). spf13/pflag because life's too short for Go's flag handling. getkin/kin-openapi for validating reqests/responses against my OpenAPI spec (in tests).

Go Package for Equality: github.com/google/go-cmp
One thing to keep in mind about reflect.DeepEqual is because of the way it is implemented you could get positive results when the values are not actually the same, see this comment for reference.
What are some alternatives?
ginkgo - A Modern Testing Framework for Go
go-testdeep - Extremely flexible golang deep comparison, extends the go testing package, tests HTTP APIs and provides tests suite
gomega - Ginkgo's Preferred Matcher Library
gotest.tools - A collection of packages to augment the go testing package and support common patterns.
realize - Realize is the #1 Golang Task Runner which enhance your workflow by automating the most common tasks and using the best performing Golang live reloading.
